initializing M-RAM

[Altera_Forum]

Q's MegaWiz does not let me setup a MIF or a HEX for a M-RAM. 

 I would like to let this device come up with a predifined pattern in the RAMs. (never changes).  Ist there a way to do this though? - over the way of the system content editor ? ... via JTAG ?   I need a way for operational mode not only during development process ...  The only idea I currently have, is to use aother small RAM, load it with a ZIP file and unpack the data while setup phase. (a strange idea, of course :D )

I get the same problem. Can you try this way: 

 use an extern eeprom, say 24c32, depending on your size. store your data in the eeprom. implemente a I2C interface and related read logic in your fpga.  whenever your fpga reset, it can read data from eeprom and init your ram.   You may need a init_done signal to let other logic know when to start their operation.

This would require a new (modified) hardware which I cannot create. Anyway there is the opportunity to do this configuration from an external PC over PCI. :cool:  

  It would have been just fine to have it ready configured in the data stream.:rolleyes:

Use M4K blocks to initialize data. You can go up to 256 KB in a stratix 2 (180) fpga.

I cannot, since the Fitter ran out of M4Ks.
